We decided to go ahead and disable the broken actions for Ubuntu 17.10.
1 of the 3 Actions is Ubuntu-specific and wasn't translated anyway because of an issue we're having with packages using meson.
By dropping the unused actions from the Actions line but otherwise leaving them in the .desktop, this won't hurt translations if we fix the bug properly later. (I did have to log out and log back in for the obsolete Actions to disappear.)
